The Latest on Pope Francis' visit to Mexico (all times local):

7:25 a.m.

Thousands of people lined up overnight and many slept out to get into the sports center where Pope Francis will say Mass in the Chiapas state town of San Cristobal de las Casas.

Officials opened the doors at 1 a.m. ahead of the Mass, which is aimed largely at the state's indigenous communities.

Jose Transito Aguilar is a Tojolabal farmer from the district of the Montebello lakes. He says he travelled six hours to reach the site.

He says "the pope seeks unity; he doesn't distinguish between people."
